上一篇博客分享了QQ共同好友的實現方案，本篇博客博主將繼續爲小夥伴們分享web日誌清洗案例。php

1、需求css

在實際生產的日誌文件中，有可能某些日誌數據並不規整，咱們須要對其進行清洗，而後用於分析；以下圖的日誌文件：html

本次的清洗規則：主要是對字段數不合法的數據進行清洗（加入標記位），而且對其中一些字段進行處理，如時間等等。java

2、代碼實現node

WebLogBean（web日誌bean類實現）jquery

package com.empire.hadoop.mr.weblogwash;

public class WebLogBean {

    private String  remote_addr;    // 記錄客戶端的ip地址
    private String  remote_user;    // 記錄客戶端用戶名稱,忽略屬性"-"
    private String  time_local;     // 記錄訪問時間與時區
    private String  request;        // 記錄請求的url與http協議
    private String  status;         // 記錄請求狀態；成功是200
    private String  body_bytes_sent;// 記錄發送給客戶端文件主體內容大小
    private String  http_referer;   // 用來記錄從那個頁面連接訪問過來的
    private String  http_user_agent;// 記錄客戶瀏覽器的相關信息

    private boolean valid = true;   // 判斷數據是否合法

    public String getRemote_addr() {
        return remote_addr;
    }

    public void setRemote_addr(String remote_addr) {
        this.remote_addr = remote_addr;
    }

    public String getRemote_user() {
        return remote_user;
    }

    public void setRemote_user(String remote_user) {
        this.remote_user = remote_user;
    }

    public String getTime_local() {
        return time_local;
    }

    public void setTime_local(String time_local) {
        this.time_local = time_local;
    }

    public String getRequest() {
        return request;
    }

    public void setRequest(String request) {
        this.request = request;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public String getBody_bytes_sent() {
        return body_bytes_sent;
    }

    public void setBody_bytes_sent(String body_bytes_sent) {
        this.body_bytes_sent = body_bytes_sent;
    }

    public String getHttp_referer() {
        return http_referer;
    }

    public void setHttp_referer(String http_referer) {
        this.http_referer = http_referer;
    }

    public String getHttp_user_agent() {
        return http_user_agent;
    }

    public void setHttp_user_agent(String http_user_agent) {
        this.http_user_agent = http_user_agent;
    }

    public boolean isValid() {
        return valid;
    }

    public void setValid(boolean valid) {
        this.valid = valid;
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(this.valid);
        sb.append("\001").append(this.remote_addr);
        sb.append("\001").append(this.remote_user);
        sb.append("\001").append(this.time_local);
        sb.append("\001").append(this.request);
        sb.append("\001").append(this.status);
        sb.append("\001").append(this.body_bytes_sent);
        sb.append("\001").append(this.http_referer);
        sb.append("\001").append(this.http_user_agent);
        return sb.toString();
    }
}

WebLogParser（日誌清洗規則類）git

package com.empire.hadoop.mr.weblogwash;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;

public class WebLogParser {

    static SimpleDateFormat sd1 = new SimpleDateFormat("dd/MMM/yyyy:HH:mm:ss", Locale.US);

    static SimpleDateFormat sd2 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    public static WebLogBean parser(String line) {
        WebLogBean webLogBean = new WebLogBean();
        String[] arr = line.split(" ");
        if (arr.length > 11) {
            webLogBean.setRemote_addr(arr[0]);
            webLogBean.setRemote_user(arr[1]);
            webLogBean.setTime_local(parseTime(arr[3].substring(1)));
            webLogBean.setRequest(arr[6]);
            webLogBean.setStatus(arr[8]);
            webLogBean.setBody_bytes_sent(arr[9]);
            webLogBean.setHttp_referer(arr[10]);

            if (arr.length > 12) {
                webLogBean.setHttp_user_agent(arr[11] + " " + arr[12]);
            } else {
                webLogBean.setHttp_user_agent(arr[11]);
            }
            if (Integer.parseInt(webLogBean.getStatus()) >= 400) {// 大於400，HTTP錯誤
                webLogBean.setValid(false);
            }
        } else {
            webLogBean.setValid(false);
        }
        return webLogBean;
    }

    public static String parseTime(String dt) {

        String timeString = "";
        try {
            Date parse = sd1.parse(dt);
            timeString = sd2.format(parse);

        } catch (ParseException e) {
            e.printStackTrace();
        }

        return timeString;
    }

    public static void main(String[] args) {
        WebLogParser wp = new WebLogParser();
        String parseTime = wp.parseTime("18/Sep/2013:06:49:48");
        System.out.println(parseTime);
    }

}

WeblogPreProcess（mapreduce主程序類）angularjs

package com.empire.hadoop.mr.weblogwash;

import java.io.IOException;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.LongWritable;
import org.apache.hadoop.io.NullWritable;
import org.apache.hadoop.io.Text;
import org.apache.hadoop.mapreduce.Job;
import org.apache.hadoop.mapreduce.Mapper;
import org.apache.hadoop.mapreduce.lib.input.FileInputFormat;
import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat;

public class WeblogPreProcess {

    static class WeblogPreProcessMapper extends Mapper<LongWritable, Text, Text, NullWritable> {
        Text         k = new Text();
        NullWritable v = NullWritable.get();

        @Override
        protected void map(LongWritable key, Text value, Context context) throws IOException, InterruptedException {

            String line = value.toString();
            WebLogBean webLogBean = WebLogParser.parser(line);
            //能夠插入一個靜態資源過濾（.....）
            /* WebLogParser.filterStaticResource(webLogBean); */
            if (!webLogBean.isValid())
                return;
            k.set(webLogBean.toString());
            context.write(k, v);

        }

    }

    public static void main(String[] args) throws Exception {

        Configuration conf = new Configuration();
        Job job = Job.getInstance(conf);

        job.setJarByClass(WeblogPreProcess.class);

        job.setMapperClass(WeblogPreProcessMapper.class);

        job.setOutputKeyClass(Text.class);
        job.setOutputValueClass(NullWritable.class);

        FileInputFormat.setInputPaths(job, new Path(args[0]));
        FileOutputFormat.setOutputPath(job, new Path(args[1]));

        job.waitForCompletion(true);

    }
}

3、執行程序web

#上傳jar

Alt+p
lcd d:/
put  WeblogWash.jar
put  access.log.txt

#準備hadoop處理的數據文件

cd /home/hadoop
hadoop fs  -mkdir -p /weblogwash/loginput
hdfs dfs -put  access.log.txt  /weblogwash/loginput


#運行程序

hadoop jar WeblogWash.jar  com.empire.hadoop.mr.weblogwash.WeblogPreProcess /weblogwash/loginput /weblogwash/logoutput

4、運行效果apache
